摘要
根据最小二乘法原理，用计算机自动分段的方法，对七种常用标准型热电偶的特性曲线进行了二阶多项式拟合，拟合精度较高。给出的七种热电偶的拟合结果，可作为有关从事热电偶测温工作人员的实用参考资料。
In the light of least square method principle,this paper carries out quadraticmultinomial fitting about characteristic curves of seven kinds of common standardthermocouples by means of automatic dividing segment method on computer.The fittingprecision is high. The fitting results of the seven kinds of thermocouples can be used aspractical reference for the personnel working on the measurement of thermocoupletemperature.
